A swivel-joint is thus 4o ments; and a'further object of the invention obtained, which permits the upper member of is to provide a communication between them the pipe tobe shifted in the manner as shown with an adjustment whereby the water disin dotted line in Fig. 3, which changes the charging from one compartment through said altitude of the inlet'of the discharge-pipe and communication into the other can be mainpermits the height of waterin the respective 45 tained by means of said adjustment at difiertanks to be changed. Thus the tank B may 5 .ent heights. be completely drained into tank A, or it can This invention is an improvement in milk be completely filled or kept at any intermecoolers patented to me January 26, 1886, No. diate point by setting the inlet of the pipe (1 334,767, and July 20, 1886, No. 345,776. at the. desired point. The tank A can be 50 l accomplish the objects of the invention by drained by setting the inlet of pipe 6 in like manner. This enables deep or shallow vessels to be set in the water by regulating the depth of water to suit.

F is the ice-chamber, which, like the tanks A B, is formed with double walls containing a heat-non-conducting filling and has a sheetnietal liningfand a cover G, with ventilator g. The ice-chamber F extends some distance above the tank B and forms an extension thereto and has blocks or brackets h connected to its opposite side walls to support a shelf H, upon which the ice is placed. This shelf is preferably simply a sheetmetal pan resting on a suitable framework of slats to strengthen and support it and having wooden slats inside to prevent injury. The pan and slats are easily removed for cleansing or other purposes, and the pan has connected to it a drip-tulie i, which is of sufficient length to extend down below the water-level in the tank B, as shown, to prevent any drippings from the ice entering the pans or plates or falling on the edibles should any be placed below. The purpose of the ice-chamber is to cool the water in the shallow tank as it passes therefrom to the deep tank when the water from the pump orspringis not sufficiently cold to reduce the milk to the required temperature. The cold air produced by the ice does not pass from the shallow to the deeper tank, but remains in the former-mentioned tank for the express purpose of reducing the temperature much lower. The shallow tank becomes the refrigeratorin which cream skim med 0E of the milk placed in the other tank is kept until needed for churning or other use, and in which edibles usually kept in refrigerators are also placed, the temperature required in this refrigerator part being much lower than that needed for the milk.

M is a slatted platform supported on legs m, so as to stand above the water in the tank. It is removable and can be changed in its position in the tank. It is designed to receive shallow plates and dishes and perhaps edibles placed loosely thereon to keep them out of the water.

To drain the tanks, the pipes is are provided, having plugs or cocks and preferably threaded at their lower ends to receive pipes for conveying the waste water to a drain or water-trough and permitting each compartment to be emptied separately and independently of the other, the one not changing the tern perature of the other. The water inlets and outlets are closed and sealed by the tubes being trappedthat is, by their being bent down and terminated under the surface of the water. Consequently there is no supply of air from the outside through said water inlets and outlets, and the ventilators are made to be opened and closed at will. There is an air-space above the water, and whenever the ventilators are opened a certain amount of evaporation of the water occurs, which evaporation lowers the temperature of the water and the cold water acts with greater efficiency than air would do to equalize the temperature and maintain frigorific conditions.

Having now fully described my invention, what I claim as new, and wish to secure by Letters Patent, is-

1. In a milk-cooler and refrigerator, one deep and one shallow tank communicating with each other through a pipe having a rocking portion with a lateral extension from said rocking portion forming an adjustable inlet, and provided, respectively, at their outer ends with a discharge-pipe and a supply-pipe, the several pipes having elbows to actas traps, the shallow tank having an ice'chamber arranged above it, provided with a shelf or pan for the ice, and a drip-tn be connected thereto and extending down below the Water-level in said tank, substantially as and for the purposes set forth.

2. In a refrigerator and creamery, one deep and one shallow tank communicating with each other through a pipe having an arm with swinging adjustment in a vertical plane, and provided, respectively, at their outer ends with a discharge-pipe and a supply-pipe, the several pipes having elbows to act as traps and the outlet-pipe having an adjustable inlet as described, the said shallow tank having an ice-chamber extensionarranged above it provided with a pan for the ice, said pan having a drip-tube, substantially as and for the purposes set forth.

In witness whereof I have hereunto set my hand and seal at Lafayette, Indiana, this 13th day of July, A. D. 1900.
